Love the super-clean art style. I like the controls, although they're 'reversed' to the way I learned isometric games back in the day (Head Over Heels, Batman 3D, Spindizzy - yep, I'm ancient). Once I got used to them, I rather enjoyed my time with this.
I found the instant teleporters and the double-jump tiles a little bit sub-par compared to the polish of the rest of it. Still amazing to get all that done in 4 days.
Not entirely sure the puzzle design works. I think I came up with some very unintended shortcuts. The puzzles were just the right difficulty however, and when I finished the game I was left wanting more. Much better to be that way round than the other! This is the first game I've finished in this jam.
